본문내용
Biological signaling : detecting extracellular signals and transducing them into intracellular changes A variety of biological signals : a few evolutionary conserved mechanism
The function of cells is tightly coordinated and integrated by external chemical signals that serve as chemical messengers and provide cell-to-cell communication.
Chemical and physical signals interact with receptors located in plasma membrane, cytoplasm, and nucleus.
Interaction of these signals with receptors initiates a cascade of events that mediate the response to each stimulus.
These pathways ensure that the cellular response to external signal is specific, amplified tightly regulated, and coordinated.
